the casing, also showing the actuating device for the operatin means for the mar er. Referring to t e drawings in detail, 1 denotes the'body portion of a vehicle, 2 e, 3 a wheel, 4 a hub, ,5 one of the vehicle L60 springs and 6 a cam ro'ecting inwar y from the inner end .of t e ub and adapte to actuate the compressor which e hereinafter referred to." The compressor, which is generally referred to by the numeral :7, is 65 mounted upon a block 8 placed upon the axle 2 and secured in position by the clam 9. The time and distance recording mec anisms are inclosed in a casing 10, which as shown, is secured to the body 1 of the ve- 70 hicle and said casing is connected to the compressor 7 through the medium of a conduit :11 in the form of a flexible tubing. 7 By setting up the recorder in a manner as stated, the ars of the axle are not im arted direct 75 to t e time and distancemec anisms w ic reduces vibration to a minimum, an urthermore, the time and distance mechanisms are cushioned through the medium of the ve hicle springs 5, which also materially *assist 86 in reducing vibration of the mechanisms'to a minimum. wing to the manner arranging the speed recorder it insures a more accurate record than would be the case the time and distance mechanisms were mounted as directly upon the axle of the vehicle as is the mode now in general use. As the time and distance mechanismslare cushioned wit the casing and as the vehicle bodyis susended upon a series bfsprings, it is evident 9o To all whom it may concern:

Be it known that we, EDWARD A. HENKLE,

a citizen of the United States, residing at Philadelphia, Pennsylvania, and Oasorous 5 H. DE LA MONTE, a citizen of Mexico, residi l at Philadelphia, in the county of Philade phia and State of Pennsylvania, have invented new and useful Improvements in Speed-Recorders, of which the following is a This invention relates to speed recorders,

articularl ada ted for use in connection with vehic es an for other purposes wherein it is found applicable.

15 One of the objects of the invention is to provide a speed recording instrument in a manner as hereinafter set forth for not only recording the s eed of travel and the distance traveled, but a so the time consumed in sto pages, all of which is very valuable as a etector to indicate the working time of the driver, to determine the number of miles the vehicle has traveled and the rates of speed at which the vehicle has been driven, w ether fast or slow.

A further object of the invention is to rovide an instrument of the class referred to with a fluid-pressure actuating means for operating the recording mechanism, said means so being operated from a moving part of the vehicle and is unusually efiicient in use.

With the foregoing and other objects in view, the invention aims to provide a combined speed, distance and time recorder, as

termed a speed recording instrument, which shall be simple in its construction, strong, durable, operating in an accurate manner, thereby obtaining an accurate record, efli oient in its use, of small com ass, readily set that by suspending the time and distance mechanisms from t e vehicle body or mount ing the same upon said body, there is ecidedly less chance of the said mechanisms curacy than would be the case if such mechanisms were mounted directly upon the axle of the vehicle.

The com ressor 7., which as'before stated, is mounte upon the axle 2', embodies a 100 inexpensive to manufacture.

In the accompanying drawings, wherein like reference characters denote corresponding parts throughout the several views Figure 1 is an elevation of a portion of a vehicle showing the adaptation therewith of a speed recorder in accordance with this inventlon; Fig. 2 1s a front elevation of a speed recorder in accordance with this invention, the

mechanism being shown inclosed in a casing, the casing bein illustrated in section; Fig. 3

is a sectional p an of a speed recorder in accordance with this invention; Fig. 4 is a lon- 'tudinal sectional view of the compressor,

' and, Fig. 5 is a longitudinal sectional view of hollow cylindrical body portion 12, enlarged at one end, as at 13, and the said enlarged end 13- is formed with an inwardly-exten in annular flange 14. Secured to the enlarged end 13 is a tubular member 15 which is of a length as to project from the enlarged end 13 forming thereby a piston chamber 16. Secured to the tubular member 15 is a closure cap 17, the latter having an interiorly-screwbeing caused to vibrate to impair their ac- 95 threaded annular flange 18 which engages an opening peripheral rod. As before stated, the spring 36 acts as a means to force the plunger away from the piston chamber 16. hespring 36 not only performs the function just set forth, but also acts as a means to move the piston toward the flange 14. From the foregoing construction and arrangement of parts it is evident that When the cam 6 engages the roller 39 the plunger 28 will be moved inwardly, the piston and the piston rod will be carried therewith, action compressing the sprin 36 between the nut 35 and 14. %Vh he iiitm 6 passes ofl the roller 30 W1 the p unger 28 outwardly and toward the flange 14.

The flexible tubing end to the nipple 21 and vertically-extending hollowmember 42 which projects through the bottom of the casing 10 and is secured to said casing through the medium of'clamping nuts 43. The hollow member 42 is provided with peripheral threads 44 which are engaged by the nut 43 and also by the coupling 45. The latter is carried by the flexible tube 11. The hollow with peripheral threads 19 formedon the mem er 15 at one end. The cap 17 is provided with a port 18 which opens into. a channel 19 formed in an enlargement 20 upon the outer face of the cap 17. Formed integral With the enlargement 20 is a screwthreaded ni ple 21 which'constitutes a continuation 0 said enlargement, and the opening 22' through said nipple forms a continuation of the channel 19. The smaller end of the body portion 12 is provided with threads 23 which are engaged by an mteriorly-screw-threaded cap 24 having 25 for a purpose to be hereinafter referred to. Arranged within the body portion 12 is a cylindrical bearing sleeve 26, one end of which terminates with one end of the body portion 12 and the other end abuts against. the inwardly extending annular flange 14. Arranged withinthe cap 24 is a suitable packing 27 which abuts'against the alining end of the sleeve 26 and body portion 12. Extending through the into the bearing'sleeve 26 is a diameter as to snugly fit said caring sleeve, but at the same time allow of a reciprocatory movement of the said plunger. That end of the plunger 28 which is arranged exteriorly of the body portion 12 is provided with a yoke 29 carrying a friction roller 30 which is arranged in the path of the cam 6 so that during the rotation of the wheel 3 the cam 6 will intermittently engage the roller 30 and direction within the bearing s eeve 26, the direction being toward the piston chamber 16. The p ger 28 intermediate its ends is formed with an opening 31 through which extends a stop pin 32 whereby the walls of said openings will limit the movement of the plunger in say, a direction edge of the member 42. v

The time and distance recording mechanisms are mounted, as before stated, in the casing 10, the latter having its top formed either direct1onthat is to toward and away from the 16. body portion 12 an is sl 52, 53, a top 54 and a wall of the casing 10 is in the form of a closure plate 56 having laterally-extending lugs 57 which are hinged through the medium of a intle 58 to the apertured lugs 59 projecting ii'om the wall 53 T e closure plate 56 is furth provided with an apertured apertured lug 1 formed upon the wall 52 and the said lugs 60, 61 are connected together through the he casing 10 is fure plunger 28 is formed at one socket 33 in which extends a piston rod 34 carrying on one end a nut 35. he piston d 34 is of a length as .to extendapast the the plunger in a direction away thermore provided with a ledge 63 arranged from the piston chamber 16. Secured to near t e lower end of the side and rear walls, that end of the piston rod 34 which extends the said ledge being continuous. Above the ledge 63 is an inwardly-extending flange 64 of the same contour as the ledge 63 and between the. flange 64 and ledge 63 is tioned a cushioning element 65 in arranged a U-shaped member 66, the latter past the flange 14 1s a piston formed of a pair of disks 37, 38, between which is clamp packing cu 39, the said cup 39 inclosing the disk 37 an engaging the wall of the piston chamber. The disk 38 is secured to the piston rod 34, and the disk 37, as well as the constltuting a support for the base plate 67 packing cup 39, is clamped to the disk 38 which carries the time and distance mechanthrough the medium of a nut 40 mounted isms The cushioning 65, in connection forms a susupon the screw-threaded end 41 of the piston with the U-shaped member 66 the flange record or to wind the time mechanism, or to position a record tape or to adjust any of the mechanisms arranged within The time and distance recording mechanisms conrprise a rotatable tape carrier travel-.

ing at a predetermined rate of speed, a tapecarrying spool from which the tape is unwound as it winds upon the carrier, a marker operating transversely with respect to the.

ta e, an oscillatory lever for the marker, shifting means for the lever and an operating mechanism for said shifting means, said operating mechanism bein operated by .the fluid-pressure actuated device. The rotatable tape carrier which travels at a redetermined rate of speed consists of a rum 68, having a peripheral flange at its top and bottom, as at 69, 70. The body portion of the drum 68 is formed with a transversely extending slit 71 and circumferentially-extending slit 7 2, this latter forming a spring tongue 7 3. The inner face 73 has secured thereto a retaining strip 74 which projects past the slit 71. The function of the slit 71, in connection with the spring tongue 73 and retaining strip 7 4, is to provi by one end of the record tape 75 can be attached to the body of the drum, and in this connection it will be stated that the end of the record tape 7 5 is inserted through the slit 71 and bent against the face of the body portion of the drum. This manner of positioning the tape can be accomplished by pressing inwardly the tongue 73 which allows of the insertion'of the end of the tape 75 in the drum. After the end of the record tape is bent to engage the inner face of the body portion of the drum, the spring tongue 73is released and the projecting end of the retaining strip 75 overlaps the end of the record tape which engages the inner face of the body porti on of the drum. To prevent the shifting o the record tape 75 when positioned upon the drum 68 a plurality of radially disposed holding arms 76 is employed, each provided with a pointed end 77. Said arms extend through the body portion of the drum '68 and puncture the tape. The inner ends of the arm 7 6 are pivotally connected to an annular flange 76 projecting from a disk 76 surrounding a boss 7 6 depending approximately centrally from the inner f the top 68 of the face 0 drum 68. The disk 7-6 carries a vertically member the casing 10. y

de means wheref therewith. The top 68 extending pin 77 which extends through a segment-shaped pin 77 is of suc length as to project from the outer face of the top 68 of the drum 68 and carries on its outer end a thumb or finger piece 77 where: by said pin 77 a can be conveniently shifted in the slot 77*. If the pin 77 'i is shifted in one direction, the disk 76 can be carried therewith, thereby moving the arms 76 inwardly. If the pin 77 be shifted in an opposite direction, the-disk 76 will be carried therewith, thereby projecting the arms so that the i ointed ends thereof will engage the tape. he disk 76. frictionally engages the boss 76, whereby the said disk is retained in proximity to the top 68 of the drum 68, but it is evident that the outer ends of the arms 76 further assist in maintaining the disk 7 6 in position and further the thumb iece 77 also acts as a retaining means for t e disk in case the disk should drop, as the finger or thumb piece 77 is of such diameter as to revent its passage through the slot 77 The drum 68, as before stated, travels at a predetermined rate of speed and for such purpose a spring motor mechanism or what may be termed a clock train is provided and which is positioned between a pair of pillar plates 78 and 78 which are spaced apart through the medium of the pillars 78. The pillar'plate 78 is supported upon the base plate 67 through the medium of the members 67. The spring motor mechanism which is indicated by the reference character 78 is geared with a shaft 78 to which the drum '68 is frictionallfi connected so that during the rotation of t e shaft 7 8the drum 68 will be revolved. The shaft 78 is provided with a shoulder 78 upon which rests the boss 76. The shaft 78 at its u per end is reduced as well as screw-threade the said reduced end being indicated by the reference character 78 and extends through the to 68 of the drum. The screw-threaded en- 7 8 of the shaft 78 carries a thumb nut 7 8 between which and the top 68 of the drum 68 is mounted a spring member 78. By screwing the nut 78 downwardly upon the end 7 8 it"willcause a binding engagement between the member 7 8 and the nut and the top. of the drum so that the drum will be frictionally connected to the shaft and rotate of-the drum 68 is provided with an opening 78 to enable access to be had to the winding staff 78 of the spring motor mechanism. In this connection it will be stated that if the opening 78 is not positioned with respect to the winding staff so that the latter could be engaged by a key to wind the mechanism, the drum 68 can be shifted manually until the opening 78 is in proper position.

The tape spool is indicated b y supportslot 7 7 'formed in the top 68 of the drum 68. The

I supporting plate 87 vides means during the rotation of the drum, the will be carried by the spool 80 will be and then wound upon the drum. The tape 75 has one face formed with a series of vertically and longitudinally extending lines respectively so as to form vertically and longitudinally extending rows of spaces indicating time and distance.

extending row of spaces is designed to record four miles, thus shortening up the length of the record for each day. ach space indicates a fraction of an hour and a fraction of a mile.

The transversely-operable marker is indicated by the reference character 82 and which extends radially with respect to the axis of the drum 68. The marker 82 is posi-. tioned so as to. engage the ta e 73, as clearly shown in Fig. 3 and is carrie in the angular end 83 of the oscillatory lever 84. The latter at its rear end is mounted upon a pivot 85 secured to the uprights 86 which extend from a pivoted as at 88 upon the base plate 67. Thel an inwardly-extending stud 89 engaging in a heart-shaped race 90 formed in one side of a 92 journaled in a pair of angular arms 93 proj ecting from the uprights 8.6. The worm gear 91' and heart-shaped race 90, in connec tion with the stud 89, constitutes a shifting means for the lever 84. he operating means for the worm gear 91 consists of a worm shaft 94 journaled in a support 96 which are carried by the supporting plate 87. The worm shaft 94 is provided with a ratchet wheel 96, lever 98- the operating means for the shifting means whereby said plate 87 can be fixedly secured in the Fig. 3. The pivoting of the p whereby said plate ed upon its pivot so that access can be had to the drum 68 to remove or position the tape 73. This shifting of the plate 87 can be had when the binding screw 102 is loosened. The said screw 102 is carried by the base plate 67.

To provide a cushioning means for the forward end of the base plate 67 the inner The verticallv face of the closure plate 56 is formed with a pocket 103 in which is mounted a cushionin element 104 adapted to engage the forward rlepnd of the base plate .67 as clearly shown in The tape carrier is adapted to make a complete revolution, say' by way of example every eighteen hours, although the rate of drum can be increased or diminspeed of the ished if desired.

enthe vehicle is standing still the operating mechanism for the marker is not in operation, but the drum still continues to operate, owing to the fact that the o eration of the mechanism for rotating the rum is not discontinued. the drum rotates it causes the tape to wind 0 the spool and upon the drum, but the duration of the stoppage of the vehicle will be indicated, owing to the fact that the marker will make a line extending in a longitudinal direction upon the tape and through onev or more spaces, andby assumed that such lin three spaces in a longitudinal direction. This will indicate that the duration of the sto page of the vehicle is fifteen minutes, as of the spaces indicates five minutes. It will now be assumed that the vehicle is traveling and the plunger 28 olperated. The lactuation of the plunger wil operate the compressor, the latter by way of example is shown as an air compressor, and shift the iston 47 upwardly, thereb ever 98 in one direction and imparting an ment to the marker. very rapidly the mark upon the extend in an approximately verti way of example it will be t e extends through The actuation tion. If the speed is lessened the mark will be at an inclination and if the vehicle stops the mark will be straight and extend in a longitudinal direction.
